摘要： An apparatus and method for casting an alloy using a unidirectional casting technique. The apparatus includes a mold adapted to contain a molten quantity of an alloy, a primary heating zone adapted to heat the mold and the molten alloy therein to a temperature above the liquidus temperature of the alloy, a cooling zone adapted to cool the mold and molten alloy therein to a temperature below the solidus temperature of the alloy and thereby yield the unidirectionally-solidified casting, and an insulation zone between the primary heating zone and the cooling zone. The apparatus also has a secondary heating zone separated from the insulation zone by the primary heating zone. The secondary heating zone maintains the mold and the molten alloy therein at a temperature below the liquidus temperature of the alloy. The temperatures within the primary and secondary heating zones are individually set and controlled.
